VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL).  It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video.  It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters.  VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.

VirtualDub 1.8.0 is out - this is a new experimental release that contains many changes I’ve been working on in the background for months. As this is an experimental release, it is recommended that you stick with 1.7.8 for production use. However, any feedback on changes in 1.8.0 is appreciated and will be used as the 1.8.x branch eventually becomes the new stable branch.

The main big change in 1.8.0 is enhanced audio support, including:

* Support for reading and writing VBR audio with correct sync.
* Input plugins can expose true VBR audio.
* Support for multiplexing in raw MP3 tracks.
* Support for selecting the source audio track when multiple audio tracks are present.
* Built-in audio decoding support for µ-law, A-law, MP2, and MP3 audio.

The VBR warning is still displayed by default, although it can be disabled in Preferences; turns out, some people were using it to detect files that were unlikely to play properly on their hardware players.
